What is an IR sensor? | FierceElectronics

Jul 29, 2019· Active IR sensors have two parts: a light emitting diode (LED) and a receiver. When an object comes close to the sensor, the infrared light from the LED reflects off of the object and is detected by the receiver. Active IR sensors act as proximity sensors, and they are commonly used in obstacle detection systems (such as in robots).

Reading analog or digital values from Infrared sensors ...

Jul 22, 2021· The sensor emits IR rays and then detects if it receives a reflection. This sensor is often used in line following robots, edge detection. The sensor allows you to sense white or black surfaces by reading the analog value from it. The measuring distance is between 1 and 8 mm. The onboard potentiometer can be used to adjust the sensitivity.

1. Confirm the pin-out from the data sheet. Two pins will be DC power in; a voltage between + and +5v, the other ground. The third pin is output, which may be floating, or may have an internal high-value pull-up resistor to the positive DC supply pin. Incorrect application of power to Vdd and ground pins can/will easily destroy the device.
